Breaks in Patio Cement

We have an outdoor patio that has been converted to and from a courtyard. The only problem is that there are these small squares that are unequal and breaking. We don't want to re-do the entire patio. Any ideas on how to seal up these square cracks?

how about cutting out some of the squares and filling them with some colored cement and make it look presentable, then seal it. u can cut out different shapes for some kind of style, and in doing all of this u will probably secure the rest by only doing some
